    El presente trabajo describirá entonces cómo el fenómeno terrorista ha modificado las capacidades institucionales en materia de seguridad e inmigración de Estados Unidos, Gran Bretaña y España, países que han sufrido directamente este tipo de ataques. Analizaré cómo aumentaron los poderes y las facultades de los servicios de seguridad, cómo se afectó el status jurídico de los ciudadanos en sus territorios y que rasgos adoptó la nueva concepción en las políticas migratorias. Tomaré en cuenta la nueva legislación excepcional y permanente, las sanciones de leyes referidas al terrorismo, y la creación de nuevos organismos. En definitiva, intentaré develar sí las nuevas leyes antiterroristas adoptadas por las diferentes democracias liberales con posterioridad a los atentados del 11/S han incidido en forma abiertamente restrictiva en el ejercicio de determinados derechos fundamentales

    Objective. The objective of the present study is to investigate the effect of rosiglitazone, metformin, ezetimibe, and valsartan (alone or in combinations) on paraoxonase (PON) activity and PON-mRNA expression in nonalcoholic fatty liver disease (NAFLD). Methods. 54 Male Sprague–Dawley rats were divided to 9 groups: chow diet group (15 weeks); methionine-choline-deficient diet (MCDD) group (15 weeks); MCDD-treated groups for the last 6 weeks with either metformin (M), rosiglitazone (R), metformin plus rosiglitazone (M+R), ezetimibe (E), valsartan (V), or a combination of R+M+V or of R+M+V+E for a total period of 15 weeks. Results. PON activities in serum and liver were decreased in MCDD rats. PON activity in serum increased significantly in all treatment groups. PON activity in liver was also increased significantly, except only in groups R, E, V, R+M+V, and R+M+V+E. Liver PON3 mRNA expression increased significantly in groups R+M, E, V, R+M+V, and R+M+V+E whereas liver PON2 mRNA expression increased significantly in MCDD, R+M, E, V, R+M+V, and R+M+V+E. Conclusions. PON activities in serum and liver were decreased in NAFLD. Treatment with insulin sensitizers, ezetimibe, and valsartan increased PON activity and reduced oxidative stress both in serum and liver
